First Great Western has apologised for the delay on the Penzance to London service on Sunday evening, stating: "A delay of this magnitude is unacceptable and a full investigation will be carried out following today's train failure."

I was once delayed on a GNER Train for 4.5hrs. The crew ran out of drinks and most food. The toilets were vile. Stranded after midnight in a quiet station. Paid £45 taxi fare but was able to claim taxi and train fare back.

I was stuck on a train with my two young sons outside Reading for about three hours while this was happening - no mobile phones in those days.
